Is a vision test required before you buy a gun? Can a blind person buy a gun? If a dealer refuses to sell a gun or ammo to a blind person is he or she violating provisions of the Americans with Disabilities Act (ADA)? From reading many of the editorials, it would believe that some gun owners are blind. They seem to have a blind dedication to guns. There don’t seem to be any limitations as to size or rate of fire. My dad was in the artillery, and he called many large canons “guns.” Tell me, what are the limits of the 2nd Amendment? I think we all know the limits of the 1st Amendment. If you require more than six rounds to dispatch a deer or game bird, you may need your eyes examined.
